| geographic stippling of nails | Regularly arranged longitudinal stippling found commonly in psoriasis and occasionally in alopecia areata. See: nail pits. (05 Mar 2000) |
|---|---|
| stippling | 1. A speckling of a blood cell or other structure with fine dots when exposed to the action of a basic stain, due to the presence of free basophil granules in the cell protoplasm. Synonym: punctate basophilia. 2. An orange peel appearance of the attached gingiva. 3. A roughening of the surfaces of a denture base to stimulate natural gingival stippling. (05 Mar 2000) |
| Ziemann's stippling | Fine dot's seen in erythrocytes in malariae malaria. Synonym: Ziemann's stippling. (05 Mar 2000) |
| basophilic | Denoting tissue components having an affinity for basic dyes under specific pH conditions. Synonym: basophil, basophile. (05 Mar 2000) |
| basophilic degeneration | Blue staining of connective tissues when haematoxylin-eosin stain is used; found in such conditions as solar elastosis. (05 Mar 2000) |
| basophilic leukaemia | A form of granulocytic leukaemia in which there are unusually great numbers of basophilic granulocytes in the tissues and circulating blood; in some instances, the immature and mature basophilic forms may represent from 40 to 80% of the total numbers of white blood cells. Synonym: mast cell leukaemia. (05 Mar 2000) |
| basophilic leukocyte | A polymorphonuclear leukocyte characterised by many large, coarse, metachromatic granules (dark purple or blue-black when treated with Wright's or similar stains) that usually fill the cytoplasm and may almost mask the nucleus; these leukocyte's are unique in that they usually do not occur in increased numbers as the result of acute infectious disease, and their phagocytic qualities are probably not significant; the granules, which contain heparin and histamine, may degranulate in response to hypersensitivity reactions and can be of significance in general inflammation. Synonym: basocyte, basophilocyte, mast leukocyte. (05 Mar 2000) |
| basophilic leukocytosis | The presence of an abnormally large number of basophilic granulocytes in the blood. Synonym: basocytosis. (05 Mar 2000) |
| basophilic leukopenia | A decrease in the number of basophilic granulocytes normally present in the circulating blood (difficult to evaluate, owing to the small and variable number normally present). Synonym: basocytopenia, basopenia. (05 Mar 2000) |
| basophilic substance | The material consisting of granular endoplasmic reticulum and ribosomes that occurs in nerve cell bodies and dendrites. Synonym: basophil substance, basophilic substance, chromophil substance, Nissl bodies, Nissl granules, substantia basophilia, tigroid bodies, tigroid substance. (05 Mar 2000) |
